Answer 1

The correct option is D

Male with thick plumose on antennae and clubbed proboscis

The mosquito have single and long proboscis which is a tube like structure. The tip of the proboscis is very sharp. It is a long needle-like antenna. The proboscis is the organ which is used for feeding. There are palps surrounding the proboscis. The proboscis is the best indication of the insect's gender. Male mosquitoes have a feather-like proboscis. The palps are long as the proboscis and have clubbed ends. The proboscis of the female mosquito is relatively smooth and they have short palps.
Thus, the correct answer is option D.
